This is the component where the feed tube slides into at the top of the water panel evaporator assembly. The nozzle attaches to the water distribution tray at the top of the unit.For use with models: 350, 360, 550, 558, 560, 560A & 568

Though not listed for the Aprilaire 440, it does work with that unit. Very easy to install. Just be careful and take your time if you go to remove it for cleaning. Use a small needle nose pliers or something similar to push the ball clip up through the frame. Then swing the nozzle end up and back in a small arc, towards the hose end, to release the back clip from the frame without a problem.

This 25 to 50 cent parat cost more than $7.00.It should have been included in the Kit, and/or the kit should have included better instructions about how to remove the original nozzle without breaking it.

Service and delivery comments:

This very small part was shipped in a rather large box, causing the shipping cost to be excessive. Why couldn't the nozzle be included in the Kit, or why coudn't the nozzle be mailed in a coushioned envelope for a fraction of the cost?
